This technique is also from Julia Andrus' book "Paper Transformed" and is a variation of the Leather Paper shown below. Spray card stock (I used a piece of manila folder) on both sides with Perfect Ink Refresher and gently rub onto the paper. Repeatedly crumple the paper to achieve the texture you desire. Iron the paper flat.
Lightly spray the paper with water and wipe off with a paper towel. This slight added moisture prevents ripping during the next step.
